Respiratory Syncytial virus (RSV)

RSV Season Has Begun

In Idaho, Respiratory Syncytial Virus (RSV) season officially began the week ending November 29, 2014 with increased activity being reported across the state.

The beginning of the RSV season, or season onset, is adapted from the National Respiratory and Enteric Virus Surveillance System (NREVSS). RSV season onset occurs in the first of two consecutive weeks during which the reported total percentage of specimens testing positive for antigen is ≥10%.

Numbers have begun to increase since November 29, 2014; RSV activity usually occurs at a low level in the summer and early fall months and then begins to rise sharply in late fall. We will continue to gather surveillance data and provide weekly updates throughout the RSV season.

We wish to thank all the participating laboratories for their contributions during this RSV season.
